I "fixed" Novella, Exaggeration and Fake Emboss. At least they work on my Gimp 2.10.14 Linux, Gmic-QT 2.7.4
But I can't be totally sure the outcome is exactly same as it was with originals, because I'm not python coder.
The Fake Emboss layer above the normal is set to soft light mode.
There is no Lanczos interpolation in 2.10 I believe, thumbs up I changed the No halo correctly.
Attached if you dare to try

They are located under Filters/Artistic.
If you have the originals and 2.8 still installed. maybe you can tell if they look correct?

Going to try the Edgey, it requires some old Iccii script.
